COOKING-STOVE.

Specification of Letters Patent No.

To all @07mm t may concern.'

Be it known that I, HENRY J. RUGGLES, of 1West Poultney, in the county of Rutland and State of Vermont, have invented certain 4new and useful Improvements in Cooking- Stoves, and that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known and of the usual manner of making, modifying, and using the same.

My improvement consist-s in enlarging the oven by carrying it out in a curved form under the smoke pipe, and in an air chamberl surrounding the Hre pot, which air chamber communicates with the external air by pipes, at the sides and at the bottom, with the Hue, as about to be described, the Hue communieating above and below with said air chamber.

In the drawing (a) is the Hre chamber, of any form, but I prefer an oval one, as shown in the figure, on either side of this chamber are grated openings at the sides of the Hre chamber outside the air chamber above named; that cover descending Hues (b) which descend outside the air chamber when they join a lower Hue hereafter described and at the back of the Hre chamber, between it and the oven, are similar openings into the air chamber; the whole of the Hre chamber is surrounded by an air chamber' (c), with short pipes (d) leading into it from the outside of the stove; another smoke Hue (e) extends back over the oven and under the boiler holes, in the usual way, from the fire chamber to the back of the oven, and thence down the back on either 9,436, dated November 30, 1852.

side of a center Hue, in two divisions (6') to the bottom, whence it runs forward in a Hue (e2) the whole breadth of the bottom, but with the center much morev shallow than the sides, owing to a projection of the bottom upward along the center from back to front, to form a Hue (e3), as clearly shown in the cross section Fig. 3. When Hue (e2) reaches the forward end of the oven, it opens into the perpendicular descending Hues b), that open downward at the front corners of the stove, and there the products of combustion enter the forward end of the center horizontal bottom Hue (e3) and pass back and up the back center Hue to the smoke pipe.

The ash pan (f) is made to put into a recess (g) under the fire chamber, which is formed for the purpose; this is also connected with the hearth, and draft plate It will be seen from the above that the front and bottom Hues uniting under the fire chamber, pass 0H in common through the center Hue; and the air entering passes through the air chamber, after being heated, is caused to enter the direct draft Hue above.

Having thus fully described my improved cooking stove, what I claim therein as new, and for which I desire to secure Letters Patent, is-

The combination and arrangement of the front and rear Hues e and b and air chainber (c), substantially as herein set forth.
